Definitions
- This invention relates to a process for making an elastically stretchable composite sheet having a comfortable touch.
- Japanese Patent Application Publication No. 1994-184897A describes a composite stretchable material comprising a stretchable sheet and a necked material bonded to the stretchable sheet at three or more non-linearly arranged spots wherein the necked material is gathering between at least two of the three spots.
- a composite stretchable material can be obtained by bonding the necked material to the stretchable sheet under a stretched condition and then contacting the stretchable sheet from the stretched condition.
- the necked material changes a rubber-like surface popular in a stretchable sheet to a comfortable cloth-like surface without damaging a desired stretchability of the stretchable sheet.
- the material previously necked by stretching it in one direction is bonded to the stretchable sheet. Consequently, the gathers are apt to distribute unevenly in a transverse direction orthogonal to the one direction at the stage that stretchable sheet is contracted from the stretched condition and thereupon the necked material is gathering. This is for the reason that, when the necked material is fibrous, the fibers lying along the side edges extending in the one direction are stretched at a ratio higher than the fibers lying intermediate regions between the side edges.
- the present invention provides the process of independent claim 1.
- an elastically stretchable composite sheet which can be more easily stretched than a composite web comprising an elastically stretchable web having upper and lower surfaces and an inelastically stretchable web of continuous fibers bonded to at least the upper surface of said surfaces of the elastically stretchable web, through steps of stretching the composite web in one direction and then contracting the composite web under an elastic contractible force provided by the elastically stretchable web.
- spots to bond the elastically and inelastically stretchable webs to each other are formed in the composite web intermittently at least in the one direction of the one direction and a direction orthogonal thereto, and the composite web is succeedingly stretched and then contracted in the one direction, wherein a first spot of the spots and a second spot lying in the vicinity of the first spot in the one direction at least partially overlap each other as one of these first and second spots is translated in the one direction.
- Fig. 1 is a fragmentary perspective view of a stock web 10 used in the process according to this invention and Fig. 2 is a fragmentary perspective view of a composite sheet 20 obtained from this web 10.
- the stock web 10 comprises an inelastically stretchable web 2 formed with inelastically stretchable continuous fibers 6 oriented at random and an elastic web 3 formed with elastically stretchable continuous fibers 40 oriented at random, both webs 2, 3 being placed upon and bonded to each other at bonding spots 4.
- the stock web 10 formed in this manner is elastically stretchable in X-direction and Y-direction orthogonal thereto, at least in Y-direction as indicated by imaginary lines.
- the continuous fibers 6 shown in Fig. 1 are in an elongated state between each pair of the adjacent bonding spots 4, 4.
- the fibers 6 in such a state are designated by reference numeral 26.
- the composite sheet 20 can be obtained in such a manner that the stock web 10 is stretched in Y-direction within breaking limits of the stretchable web 2 and the elastic web 3 and also within an elastic limit of the elastic web 3 so that the continuous fibers 6 of the stretchable web 2 may be plastically deformed and thereby may become more fine. Then this stock web 10 is contracted under an elastic contractible force provided by the elastic web 3 to obtain the composite sheet 20. When the stock web 10 is stretched, the web 10 will need a force to stretch both the stretchable web 2 and the elastic web 3. However, when the composite sheet 20 is stretched, the sheet 20 will need only a force to stretch the elastic web 3, because the stretched fibers 26 of the stretchable web 2 are merely reoriented so as to extend in Y-direction. In this manner, the composite sheet 20 is elastically stretchable more easily than the stock web 10.
- Fig. 3 is a plan view of the stock web 10 as viewed directly above the stretchable sheet 2, in which the component fibers 6 are not shown.
- each of the bonding spots 4 has an oval shape defined by a major axis of a length p in X-direction, a minor axis of a length q in Y-direction, a first end a lying at the right hand side and a second end b lying at the left hand side as viewed in Fig. 3.
- Each pair of the bonding spots 4, being adjacent is X-direction, for example, the bonding spots 101, 102, or 102, 103 are spaced apart from each other by a distance r which is smaller than the length p of the major axis.
- the bonding spot 102 When the bonding spot 102 is described to be adjacent to the bonding spot 101, it should be understood that the bonding spot 102 lies sufficiently near the bonding spot 101 and will at least partially overlap the bonding spot 101 if the bonding spot 102 is translated in X-direction.
- the respective arrays 100, 200, 300 ?? of the bonding spots 4 are spaced one from another by a distance m in Y-direction.
- the respective bonding spots 201, 202, 203, 204 Vietnamese subset of the second array 200 are arranged relatively to the respective bonding spots 101, 102, 103, 104 Vietnamese to the respective bonding spots 101, 102, 103, 104 Vietnamese to the respective bonding spots 101, 102, 103, 104 Vietnamese array.
- the bonding spot 202 lies between the bonding spots 101 and 102
- the bonding spot 203 lies between the bonding spots 102 and 103
- the bonding spot 204 lies between the bonding spots 103 and 104. If the second array 200 is translated in Y-direction, the bonding spot 202 will partially overlap the bonding spots 101 and 102.
- the bonding spot 203 will partially overlap the bonding spots 102 and 103.
- Relationship established between the bonding spots 201, 202, 203, 204 Vietnamese of the second array 200 and the bonding spots 301, 302, 303, 304 Vietnamese of the third array is similar to the relationship established between the first array 100 and the second array 200.
- a group of the bonding spots 4 which are adjacent one to another in Y-direction include, for example, the bonding spot 202 and those which will partially overlap the bonding spot 202 when translated in Y-direction, i.e., the bonding spots 101, 102, 301 and 302.
- the respective bonding spots 101, 102 Vietnamese, 102 Vietnamese, 201, 202 ?? 301, 302 Vietnamese are arranged so that they may at least partially overlap one another as they are translated in Y-direction, more preferably, the spots adjacent one to another in Y-direction as seen in Fig. 3 are aranged so that they may at least partially overlap one another as they are translated in Y-direction.
- plastic deformations of the continuous fibers 6 occur between each pair of the bonding spots 4, 4 being adjacent in Y-direction in the case that the stock web 10 comprising the continuous fibers 6 distributed at random is stretched in Y-direction.
- Such plastic deformations easily elongate the continuous fibers 6 to more fine fibers.
- the bonding spots 4 can advantageously function for the continuous fibers 6, preferably, the dimension p is at least 0.3 mm, the dimension q is 0.2 - 6 mm, the dimensions e and f are at least 0.3 mm and the distance by which the bonding spots are spaced one from another in Y-direction is 0.5 - 30 mm.
- the bonding spots 4 preferably occupy 5 - 20 % of the entire area of the stock web 10.
- the bonding spots 4 are illustrated to be identical in their shapes, it is possible without departing from the scope of this invention to alter their shapes and layout.
- the respective arrays including the first array 100 may continuously extend across the full width of the stock web 10.
- the bonding spots 4 are formed intermittently in X-direction so that the composite sheet 20 may be stretchable in X-direction as well as in Y-direction. Stretchability of the composite sheet 20 in X-direction will be reduced if the bonding spots 4 continuously extend in X-direction.
- the continuous fibers 6 may be selected from a group of fibers including homopolymer, copolymer and terpolymer of propylene.
- the elastic web 3 formed with elastic fibers 40 may be replaced by film made of plastic elastomer.
- the process according to this invention for making the elastically stretchable composite sheet facilitates the continuous fibers of the stretchable web as one component of the stock web to be evenly stretched in the stretching direction of the stock web as well as in the direction orthogonal thereto as the stock web is stretched. This is brought by the construction of the stock web that the bonding spots of the stock web are formed intermittently in the stretching direction of the stock web and uniquely distributed so that the bonding spots will at least partially overlap one another if these bonding spots are translated in the stretching direction. In the composite sheet obtained in this manner, the continuous fibers form the gathers evenly not only in the stretching direction but also in the direction orthogonal thereto.
